MACHINERY CORPORATION, OF PATERSON, NEWJERSEY, A CORPORATION OF NEW JERSEY HEEL COVER TUCKING MACHINE- PATENT OFFICE Application filed January 4, 1930. Serial No. 418,641.

This invention relates to cover tucking apparatus, and is herein exemplified as em-y bodied in a machine for tucking the edge portion of a heel cover into a channel in a heel lof a typey which has come into use in rrecent years.

It is an object of the inventionr to provide y an improved cover tucking apparatus which,

" iwhile simple in construction, will be easy to operate and capable of .tuclring heel covers into channelled heels very Vrapidly and smoothly.

Y With this object iii-view, an important'fea f ture of the invention consists in the combina,- tion with a steppedtuching tool of means for imparting to said tool a tuclring movement which is preferably, although not necessarily,

a rocking movement.4 Such a tool may com-k ing provision for imparting continual rocking movement to a cover tuclring tool, whether the tool be stepped or not.

A still further feature of the invention resides in the combination-with a cover tuck- A ing tool of means for imparting to said tool a rocking movement about a point in its tuclringportion. In the case of a tool comprising a stepped blade the rocking movement would preferably Occur about a point substantially inthe stepped portion of the blade.

In the illustrated machine the tuclring tool is mounted upon the end of a rock shaft which may derive movement, for example, from a drive shaft through suitable power transmitting connections, shown herein as comprising a crank upon the drive shaft co-operating with a. slotted rocker member upon the rock shaft to impart continual rocking movement in which is secured a crank pin 16,V eccentric to the aXis of the shaft 12. Loosely engaged l f i30- vention is to be yrecognized in a machine hav-v 82 in Figs. 3 and 4. Y I

It will be apparent that rotationof the .shaft lrineither direction will impart a These and other features and advantages ofkk the invention will be better understood and appreciated from reading the. following detailed description of one embodiment thereof in'connection with the accompanying drawings, in which 'i 4 Fig. 1 is a view in side elevation, partly in section, of a machine embodying the invention: Fig. 2 is a sectional detail view on the line.

Fig. 4 is a perspective View, showing t-he manner in which the work is presentedto the Ymachine and operated upon.

In the drawings 10indicates a Vsuitable base or frame in and upon which the working parts of the machine are supported. Suitably journaled inthe frame 10 is a continually rotating drive shaft 12 carrying ak crank disk ,14

by the crank pin 16 is a block 18 adapted to slide-in a slot 2O formedV in a rocket member 22 which is rigidly secured to a rock shaft 24, also journaled in the frame 10. n

At the right-hand end of the rockV shaft 24, as viewed in Fig. 1, there is provided an upwardly bent rocker arm 26 to which is se'-L cured, by a screw 28, a tuclring tool 30 comprising a thin blade. of peculiar formation in that the portion of its edge which engages the heel cover material andftucks it into the f channel in the heel is stepped, as

shown at f continual rocking movement to thev rock shaft 24, including the rocker arm 26 whichcarries the tucking blade 30, the arrangement being las a consequenceof which acontinual rocking` movement about the said point is imparted to the tucking blade.y This is well shown in.y

be adjusted. f

Fig. 3 wherein the dotted lines represent one of the extreme positions of the blade.

Accurate presentation of the heel to the machine is facilitated by side and breast gages shown in Figs. 1 and 4 wherein 34 indicates a side gage having a heel engaging face 36 which is curved to an approximation 0f the average curvature of the heel to be operated upon. The gage 34 is sustained by a vertically adjustable upright 38 provided with a slot 40 through which passes a clamping screw 42 threaded into a horizontally adjustable carrier 44. Adjustment of the carrier 44 is provided for by a screw 46 having threaded engagement with a flange or web-48 of the machine frame l() and swiveled engagement with the carrier, as shown at 50. A clamping bolt 52, passing through a slot 54 in theY carrier, provides for securing the carrier firmly in any position to which it may The breast gage comprises a disk 56 which also constitutes a guard for the tucking blade. The said disk is freely rotatable upon a stationary pin 58 screwed into an overhanging arm 60 which is bolted adjustably to an upright 62 arising from the frame 10.

A channeled heel to which covering material is to be applied is illustrated at 64, the channel in the heel into which the covering material is to be tucked being shown at 66 and the sidefand breast coversfor the heel being shown at 68 and 70 respectively.

The heel covering material is applied .smoothly to the heel with the marginal portions of the cover overlying the channels in the heel as shown at the left in Fig. 4. The shaft 12 rotates at high speed and a continu al high speed rocking movement is, therefore, imparted to the tucking tool 30. The heel with the applied cover is presented to the rocking tucking blade, the gages 34 'and 56 being so'adjusted as to facilitate the positioning of the heel to cause the point of the blade to enter the channel 66 and acting to steady and guide the heel. The stepped formation causes the tool to force the cover material more and more deeply into the channel in successive stages as the tool is rocked and this stepped progressive tucking action continues from one end of the channel to the other as the heel is moved lengthwise along the face 36 of the side gage 34, until the tucking is complete.

The rapidly rocking tool operates to tuck the heel cover into the channel in the heel rapidly and smoothly, the stepped forma-- tion of the tucking blade not only making the operation very easy,- but overcoming any tendency of the tool to crowd the cover material ahead of it and form wrinkles in said material.

Having described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a heel covering machine, the combination of a stepped tucking tool and means for imparting tucking movement to said tool.

2. In a cover tucking machine, the combination of a stepped tucking tool and means for imparting rocking movement to said tool.

3. In a. cover tucking machine, the combination of a tucking tool and means for imparting continual rocking movement to said tool.

4. in ka cover tucking machine, the combinotion of a stepped tucking tool and means for imparting continual rocking movement to said tool.

5. In a cover tucking machine', the combination of a tucking tool and means for imparting to said tool movementabout a point in its tucking portion.

6. In a cover tucking machine, the combination of a tucking tool and means for impart-ing to said tool rocking movement about a point in its tucking portion.

7. In a cover tucking machine, the combination of a tucking tool and means for imparting to said tool continual rocking movement about a point in its tucking portion.

8. In a cover tucking machine, the combination of a tucking tool comprisingk a blade having a stepped edge and means for imparting to said tool rocking movement about a point substantially in said stepped edge.

9. In a cover tucking machine, the combinotion of a rockshaft, a tucking tool mounted upon the endof said shaft, and means for imparting rocking movement to said shaft.

10. In a cover tucking machine, the combination of a continually driven rock shaft and a stepped tucking blade mounted upon the end thereof.

11. In a cover tucking machine, ,the combination of a rotating drive shaft, a rock shaft, power `transmitting connections between the drive shaft and the rock shaft, and a tucking tool mounted upon the rock shaft.

12. In a cover tucking machine, the combination of a rock shaft and a tucking blade having a stepped edge mounted upon said sha-ft, the axis of the shaft passing substantially through said stepped edge.

18. In a cover tucking machine, the combination ofV a rotating drive shaft, a rock shaft, a slotted rocker member upon the rock shaft, a crank upon the drive shaft co-operating with said member to impart continual rocking movement to the rock shaft, and a tucking tool mounted upon the rock shaft.

In testimony whereof I have signed my name to this specification.
